RAILWAY BRAIKE-BEAM.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed August 5, 1908. Serial N 0. 447,022.

T 0 all whom it may concern:

Be it known that I, SETH A. OnoNE, a citizen of the United States, and aresident of East Orange, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in RailwayBrake-Beams, of which the following isa specification.

The invention relates to improvements in railway brake-beams, and itconsists in the novel beam hereinafter described, and particularlypointed out in the claims.

The object of my invention is, more p articularly, to provide animproved and highly eflicient compression member for trussed brakebeams,and more especially to construct said member from a structural beamsection, preferably ofT-shape in cross-section, in such manner that atits end'portions it will form recesses for the end portions of thetruss-rod, receive the bearing-sleeves for the brakeheads and afford mXimum strength to resist the power applied against said end portions inservice.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompa nyingdrawings, in which:

Figure 1 is an elevation of one end portion of a trussed brake-beam,with the bearingsleeve thereon for the brake-head, not shown Fig. 2 is alike view of one end portion of the compression member of the beam, thetruss rod and bearing sleeve being omitted; Fig. 3 is a transversesection through the compression member and truss rod of the beam on thedotted line 3-3 of Fig. 1; Fig. 4 is a like section through the beam onthe dotted line 4-4 of Fig. 1 Fig. 5 is a like section through the beamon the dotted line 5-5 of Fig. 1; Fig. 6 is a like section through thesame on the dotted line 6-6 of Fig. 1, and Fig. 7 is a section through amodified form of the compression member on the line of the section ofFig. 4, this modification consisting in upsetting the web of the beam inlieu of splitting it to straddle the truss-rod-in the manner shown inFig. 4.

In the drawings, 10 designates the compression member, 11 the truss-rod,and 12 the sleeve securing the corresponding ends of said compressionmember and rod together and adapted to receive, in a well understoodmanner, the brake-head, not shown.

The truss-rod 11 is commonly used in trussed brake-beams and requires nodetailed description; it is customarily threaded at its ends to receivesecuring nuts 13 which bind against the outer oblique ends of thesleeves 12.

The compression member 10 is preferably made from a rolled commercialbeam of T- shape in cross-section, and in the production of the member10 therefrom I do not neces sarily modify the beam section except at itsend portions, which I do reconstruct in respect to the web 14 and flange15.

My invention resides, therefore, in a novel construction of the endportions of the brake-beam, and in carrying out one form of my inventionI split the web 14 to create lips 16 (Fig. 4) which receive between themportions of the rod 11, "and outwardly beyond the lips 16 I compress theweb 14 and flange 15 into a solid end 17, which outwardly be yond thelips 16 is recessed, as at 18, to continue the recess for the truss-rod11. In the formation of the solid ends 17 I preserve the generallongitudinal plane of the outer central line of the flange 15, asdenoted in Fi s. 1 and 2, and crowd the side portions of t e flange 15in a direction toward the web 14 and press the web in line with its edgein a direction toward the middle of said flange, whereby a solidintegral end 17 is produced which has a straight outer edge, divergingsides and a concave inclined inner surface 18, said end decreasing inthickness from about the outer ends of the lips 16 to the outer end ofthe beam, as shown by the relative thicknesses of metal in the end 17represented in Figs. 5 and 6.

My purpose is to produce solid ends 17 at the end portions of a rolledflanged commercial section and to maintain in said ends the maximumamount of metal disposed to secure the greatest amount of strength andefliciency. I therefore seek to avoid cutting away portions of the beamin creating the compressed ends 17 but find that in the use of somerolled sections it is necessary to clip ofi a portion of the outer endof the web 14, outwardly beyond that part used in forming the lips 16,prior to the compression of said ends so that I may not have too muchmetal to be conveniently confined within the sleeve 12, whose diameteris limited to the requirements of standard brake-heads. The li s 16 areformed to preserve or leave in the earn the maximum quantity of metal atthe inclined end portions of the rod 11 rather than to afford seats orrecesses for said rod, and in lieu of forming the lips 16 the may beleft in the beam by upsetting the web thereof in the manner shown inFig. 7, said web being upset in a direction toward the flange of thebeam and thereby thickened in affording space for the inclined endportions of the rod 1.1.

In both the constructions shown inlTigs. 4 and 7, the metal of the webis displaced to allow the rod 11, at its ends, to take the properangular relation to the beam, so that the n'iaximum strength. may besecured in the beam. acter with the exception that its interior socketconforms to the new shape of the end 17.

What I claim as-my invention and desire to secure by Letters Patent, is:

1. In a brake-beam, a rolled flanged compression member having, at eachend, the web and side portions of the flange, compressed into a solidintegral end forming a recess for the end of the truss-rod; substantially as set forth.

2. Ina brakebeam, a rolled flanged compression member having, at eachend, the web and side portions of the flange compressed into a solidintegral end having diverging sides and a concave recess between saidsides for the truss-rod; substantially as set forth.

3. In a brake-beam, a rolled flanged compression member having, at eachend, the web and side portions of the flange com pressed into a solidintegral end. forming a re cess for the end of the truss-rod, and theWeb of said member inwardly from said ends same metal l The sleeve 12 isof customary charbeing displaced to allow the ends of the rod to havetheir proper inclination; substantially as set forth.

4. In a brake-beam, a rolled flanged compression member having, at eachend, the web and side portions of the flange com pressed into a solidintegral end having diverging sides and a concave recess between saidsides for the truss-rod, and the web of said member inwardly from saidends being displaced to allow the ends of the rod to have their properinclination; substantially as set forth.

5. In a brake-beam, a rolled flanged compression member having, at eachend, a portion of the web split and. spread open to receive thetruss-rod, and beyond the same having the web and side portions of theflange compressed into a solid integral end forming a recess for theouter portion of the truss-rod; substantially as set forth.

6. In .a brake-beam, a rolled flanged compression member having,'at eachend, a portion of the web split and spread open to receive thetruss-rod, and beyond the same having the web and side portions of theflange compressed into a solid integral end having diverging sides and aconcave recess between said sides for the truss-rod; substantially asset forth.
